(Just in case this is not already in 0.8) The dialog box for adding an impediment does not have an asterisk next to the details field, yet it is required. Either change it so that the details are not required (preferred), or add the asterisk. In fact, I'm not sure it's even necessary to have separate title and details fields for impediments. Just one text box should suffice (with the text truncated at the times that displaying a title would normally be called for). -- I'm wondering about the same thing for tasks, BTW.
